156	156	A rather central aspect is also of course that the robot should really take a walk outside and not inside the lab room. Preferably, the test should have been performed in an actual garden in order to be able to assess its capabilities in the appropriate terrain. This would also make it possible to make the walk more elaborate and longer since observations during the evaluation show that participants would have rather had a longer and more extensive walk, which was not possible in the lab environment.

158		-In future studies, the number of participants should be considered, as well as testing the design on PwD and in an actual garden or at the very least a bigger space. The walk should preferably be more extensive and perhaps incorporate aspects of the garden or the environment into the conversation to make the experience more immersing, for example by referring to the flowers that are blooming in the garden and trying to draw PwD's attention to these aspects and create conversations from this. Hopefully, adjustments like these would improve the overall quality of the walk. Further improvements to speech recognition are needed, as well as the smoothness of the walking and the aspect of the participant's distance to the robot. Perhaps if the less realistic aspects discussed above are minimized, a robot that feels more realistic would result in participants listening to the actual prompts given to a larger extent, rather than going into the experiment with a predisposed idea of what they are going to do or answer and would also perhaps deter the participants from tending to reply positively. Further, the motivational prompts were certainly customized to the persona, but further customization could have been considered. For example, it would of course be far greater if the robot has some ability to adapt to the conversation more or less "in real time" by taking in the information given by the PwD and replying in an appropriate manner. Further, intonation could be interpreted and perhaps also shape the responses and prompts of the robot. These things are rather difficult and due to limitations in the current hardware and software may be hard to implement, but it is essential to consider these aspects for future work.

Finally, implementing route verification using GPS and adding safety monitoring features, could significantly broaden the applicability of the robot system.
